A3Architects is excited to announce that Alison Alessi, Architect, Leed Ap has recently completed training to be a Certified Passive House Consultant and is one of less than 300 certified Passive House Consultants in the US. Through the energy modeling program Passive House Planning Package (PHPP) over 90% reduction in energy use vs. a typical code built house is possible, even in the northeast climate zone. If renewables are used, net zero is easily accomplished.
“A Passive House is a very well-insulated, virtually air-tight building that is primarily heated by passive solar gain and by internal gains from people, electrical equipment, etc. Energy losses are minimized. Any remaining heat demand is provided by an extremely small source. Avoidance of heat gain through shading and window orientation also helps to limit any cooling load, which is similarly minimized. An energy recovery ventilator provides a constant, balanced fresh air supply. The result is an impressive system that not only saves up to 90% of space heating costs, but also provides a uniquely terrific indoor air quality.” -Passive House Institute US
